all whom t may concern.'

Be it known that I, Zen OIl the United States, residing at Chicago,inthe county ofv Cook and State of 5 Illinois, have invented new anduseful Improvements in Rail Anchors,y of which the following is aspecification.

My invention'relates to devices for preventing@ the longitudinal creepof railway rails, these devices being commonly called rail anchors,anti-Creepers, or rail stays.

One of the principal objectsot the invention is toprovide a rail anchorof simple and compact construction which will Amaintain a reliable holdon the rail, as vagainst the tiendency of the device to vibration orother disturbing influences, and

which may be veryquickly and conveniently put in place on the rail orremoved therefrom, if occasion requires. i'

A further Object is to provide a rail anchor which can be used `withrails havingr somewhat different rail base contours, particularly with.rails having base flanges which vary in thickness. lt iswellrknownthatrails'of different mikes, evenwhen of the sameweight per linearunit, differ somewhat inthe 'dimensions and contours of.

their bases. Rails ot the same make sometimes have slight diiiierencesdue to the wearinfrof the rolls employed in manufacturing them. K.

Bly invention contemplates rail anchor a part et which is adapted toextend around and moved transversely on'the rail base in applicationthereto. anda further object of the invention is to provide, in ananchor ot this sort. means associated with the rail base whereby theangularity of thesurface fecting the practical efficiency of thedevice.`

POOR, a citi` become loosened byV upon which one portion of suchtransversely i The invention consists in the novel -arrangements andconstructions to be; hereinafter described and claimed torcarrying outthe above stated objects and such other ob- .jetts as will appear fromthe followingdesc-ription. f

The invention is illustrated in apoertain preferred embodiment in theaccompanying drawings, wherein:

Figure 2 is a perspective view o' a tapered. block which is used tovprovide a surface oi" increased angularity with respect to the bottomface pf the rail for one portion ofthe transversely movable memberl tobear upon;

Like characters of reference designate like I parts in the severalfigures ot kthe drawings.

Reterring Erst to Figs. l to 2,-inclusive. l0 designates a railroad railand l1 one of the cross ties on which. theJ rail is supported.. The railshown .in Fig. 'l isotthe standard American type. the ton surfaces ofthebase flanges eachl'reinp: straight and 'formed at an of approximately 13degrees to the bottom ot the base thereof. l

The rail anchor comprises a. body member adapted to extend under and`around the base ianges 12 ot the rail, designated i@jeneralljf hv thereference character and a tapered lblock 14 for provi:lin`,Y a surfacefor one portion of the body member'to bear upon which surface is oi'ygreater angularity with Yrespect to the bottomv face of the rail "hanthat of the upper surfacel of ythe portion ot the rail upon which theblock 14 bears. Preferably the block isplaced on .top of one of the baselianges l2 or'V the rail and may relative .to lthe body memberY or theblockma'y be providedwith twoV depending lugs i 16 which are spacedapart and are adaptedto hook over the edge ofthe base flange. If desiredboth the groove and the lugs may be used.v

The body member 13 is preferably constructed of slightly resilientmaterial and as follows: The extremities of the body member are bentover to form jaws 17 'and'18, respectively, these jawsfbeing formed sothat the -jaw 18 is approximatelytwice as long as the jaw 17, and itsopen portion 19 issomelwhat wider than that of the jaw 1,7. Intermediateits ends, and preferably nearer the jaw 17 than the jaw 18, the bodymember is bent upwardly so 20 which is adapted to bear against thebottom surface of the rail base. When the body member ris thusconstructed the proportions and shape'of the jaws 17 and 18 seat 2O whenthe device is not applied to the rail, Iare Vsuch that if thatfthesurfaces 1,7va

the top'slur'faces of the right-,hand flange 12 and theblock 14, thetopsurface of the seat 20 will be somewhat above the plane of vthe bottomof the rail base in other words, in applying the device to the rail, theseat 20 has to be forced awayfrom thejaws 17 and 18, that is downwardlyintol a lower plane. The engagements of the anchor with the rail baseare such that the body of the anchor is distorted and under a strainwhen applied to the' rail.`

jaw.

, strain as the jaw 17 is The extremity ofthe jaw 18 is preferably bentso as `to provide a shoulder 18". Movement of the body membertransversely of the rail, in the direction'to placeit under a strain,causes the edge of the rail engaged by the jaw 18 to seat behind theshoulder 18b `formed on vthe under surface ofy the ber in that directionis resisted by the body member Jbeing placed under an increasing forced`further up thetapered bearing surfaceof the block 14. Movement in theopposite direction, or baaltward, is resistedbecause the vangularity ofthebearing surface 18, formed on the un- Vderzsurfaceof the -the bottomface oftherail. is greater than .that `of thefsurface 18a.

.tion of applying the vdevice is completed by driving the jaw 17 uponthe block 14 by meansI of a sledge-hammer or t-he like, the finalposition of the body member being 4substantially as shown in full linesin F 1. The jaw the body the rail 17 rides in the groove- 15 as memberis moved transversely onto base and the vvertical portion of 17 engagezsthe inner faces of the The tendency of the body memoriginal shaperesults `in an extremely Vstrong gripping vaction on the rail base,which isr sufficient to hold the ,device in position onV the railagainst vibration or other disturbing influences. Backward movement ofthe body member on the rail vbase is resisted by vthe shoulder 18bbeinginfront of and engaged by the edge of the rail base. The vents therail from creepingin the direction from the anchor toward the tieagainst which the anchor bears, thatis tosay toward the right in F ig.3. y

The device is of simple and compact construction and may be very quicklyapplied to or removed from the rail. Another advantage of the device isthat it may be used on rails, thebases of which have somewhat differentcontours. The jaws are of suicient length to take care of slightdifferences in width of a given rail base. The tapered block provides asurface for of the body member to bea-r upon whichsurface is of greaterangularity with respect to the bottom face of the rail than that of theupper face of the flange upon which the block bears which adds to thetake-up of the device and permits of morevvariation in the rail basecontour and in the manufacture of the body member. In other words, withthe takeupA block, there maybe considerable variation in the thicknessof the .rail base .andin tbe relative positions of the jaws 17 and 18with respect to the seat portion .20.

.without 'affectingtheeticiency of the device togrip the base of therail.

lullig. 4l, have shown` therlevice .as applied to rail 21 which is ofthestandard British type, the topsurfaces 22 and 23.01: the Vbase4tlangesaf't beingformed at angles degrees,` respec- Tfn el and V5l-phave. illustrated va :modified form of tapered block to provide anenseat20 bears aga-inst device effectively preone portion gaging or'bearing surface of greater anguto the upper face of the tween eitherone of the jaws jacent flange,

of a British type of raih The bottom of the blockQ is formed to fit thetop surfaces of the base Aflanges of the rail. TheV block preferablyextends inwardly on the flange Q4 and abuts against the vertical web ofthe rail. The block preferably is formed with a groove`26 and lugs 27which are engaged by the jaw 17 to prevent longitudinal movement of theblock on the rail base.

So far as I am aware, I am the first in the art to provide for the useof a take-up block such as thatabove described, interposed beof `adevice of the type shown and the upper face of the adthe block being soarranged that, upon a movement of the 'body and jaws transversely withrespect to the rail and with respect. to the block, the device is causedto tighten about the rail, either by reason of a differential action atthe opposite sides of the rail, or otherwise. `While I have shown thejaws 17 and 18 of different length, with reference to the position ofthe bearing portions of the jaws with respect to the position of theintermediate seat 20 understood that I do not wish to be restricted tothis particular arrangement eX cept so far as the claims arelspecifically so limited, While the wedgey 14 isv shown in vengagementwith the flange at the left in Fig. 1, with the thicker portion of thewedge disposed 'adjacent to the vertical web ofv the rail, it will beunderstood that I do not wish to' be restricted-to this feature exceptso far as the same is specifically claimed, inasmuch as it is evidentthat the important characteristic ofthe operation of the wedge is thatthe jaw underneath which the wedge is interposed shall be moved upwardlywith respect adjacent flange as the `device is moved from itspreliminary applied position to the operative vtightened position.
